[name]Lily[/name]-[name]Mae[/name] - I hear both [name]Lily[/name] and the double-barrel -[name]Mae[/name] names are huge in the UK right now, potentially even really overdone. I adore [name]Lily[/name], but I’m not so keen on [name]Lily[/name]-[name]Mae[/name]. Not because of the trend–I just don’t really like [name]Mae[/name] in general. I think just [name]Lily[/name], or even something like [name]Lilia[/name], [name]Lillian[/name], or [name]Liliana[/name], nn [name]Lily[/name], would be fabulous.
Elliah - I think the spelling could be easier. [name]Elia[/name], or [name]Elea[/name], for example? I think unique spellings could be a terrible heartache, personally. I like the idea of [name]Eliana[/name] even more, though.
Elliese - I think [name]Elise[/name] is lovely, but why change it to Elliese? Again, I think the spelling would be a problem. I think most people would assume “Elliese” was either “[name]Elise[/name]” or “[name]Elyse[/name]”.
[name]Emma[/name] - [name]Emma[/name] is just lovely. Classic, sweet, charming. It’s popular, but still all sorts of wonderful. 
I have a cute little second cousin named [name]Emma[/name]. I prefer it as a MN for that reason, though–[name]Emma[/name] is a lot more refreshing as a MN, I think.
Robyne - it feels dated to me, sorry, but it’s nice enough. I prefer other bird names, like [name]Wren[/name], [name]Lark[/name], and [name]Sparrow[/name]. And again, I would prefer it spelled [name]Robin[/name]/[name]Robyn[/name].
[name]Molly[/name] - a name that seems to be getting quite popular both in the US and the UK, but I’ve never really seen the appeal. I know a [name]Molly[/name] that just graduated high school, and when she was born, I remember not liking the name, and my opinion hasn’t changed much since, haha. It’s a nice name, just not my cup of tea.
[name]Madison[/name] - I think it’s heyday is finally over–it’s been going down for a couple years now. At least here, it’s incredibly trendy, overdone, and has a ton of terribly spellings (like [name]Madyson[/name], Madysyn, [name]Madisyn[/name], Maddisyn, Madysynne, etc.), and I think it’s much more attractive on a little boy, anyway. Sorry.
[name]Ella[/name] - [name]LOVE[/name] [name]Ella[/name]. Despite it’s popularity, I think it’s a great pick, very vintagey and sweet. I also love [name]Eleanor[/name] nn [name]Ella[/name].
[name]Ellie[/name] - [name]Ellie[/name] is another one I hear is really overdone in the UK. I’m not from there, but I have friends who talk about names from there, so I hear things. [name]Ellie[/name] has never really been my thing, but I think something like [name]Elise[/name], [name]Eliana[/name], or [name]Ella[/name] nn [name]Ellie[/name] would be nice.
[name]Savannah[/name] - nice, but I’m not sure I love it. I do love the nns [name]Annie[/name], Savy, and [name]Ava[/name], though.
[name]Saskia[/name] - charming! A real stunner from your list. It’s not my favorite ([name]Ella[/name] or [name]Lily[/name] probably would be), but I would be most impressed to meet a [name]Saskia[/name] out of all the names on your list.
[name]Grace[/name] - adore. [name]Grace[/name]'ll be somewhere in my first daughter’s name, to honor my grandmother, but even if it weren’t, I just love it as a name. It’s so simple and classic and gorgeous.
[name]Rosie[/name] - I must admit, I’m not the biggest [name]Rose[/name] fan. And I like just [name]Ro[/name] over [name]Rosie[/name], which seems too sickly-sweet to me (although I do adore [name]Posy[/name] and [name]Sosie[/name]!).
[name]Hope[/name] - it has a nice meaning, but I’ve always liked other virtue names more. [name]Hope[/name] has always seemed a bit plain for me.
[name]Faith[/name] - another nice virtue name, but I’ve never been able to get behind it. I like it more as a MN, personally.
Good luck!
